A mum died just two days after being admitted to hospital with what she thought was flu.

Lisa Cheshire, 44, died on Valentines Day, from organ failure caused by pneumonia.

The mum-of-two had the previous week complained of flu like symptoms, such as a headache and cough, and had taken a few days off work.

Her partner of 19-years, Stephen Smith, said like anyone else with flu Lisa “lay on the couch, took paracetamol and cough medicine”.

However, after believing she was “slightly picking up” on Friday, he said she quickly deteriorated and on Monday he took her to the doctors, who immediately called an ambulance to take her to hospital.

The dad-of-two, who is now the sole carer for his 11-year-old daughter Mollie and 15-year-old son Luke, said he wishes they had known earlier what Lisa had.

He said: “She had just lay on the couch, taking paracetamol and cough mixture because really that is what you are told to do if you think you have flu.

“I never gave it a thought that anything like this could happen.

“And 99 times out of 100 this would never happen and usually when you think you have flu, you do, but unfortunately in Lisa’s case it went horribly wrong.

“I can’t believe it.”

Stephen said Lisa was devoted to her children, who he said are “missing her terribly” and was very protective over them because she “just loved them so much”.

In a heartbreaking tribute to her mum and “best friend”, 11-year-old Mollie, who will soon be sitting her SATS said: “My mum will always be looking down on us and telling me and Luke to stay strong and keep up with school and pass are GCSEs and SATS.

“Words can’t explain how much I love my mum, always will do and always have, I love her to the moon and back and more and always will.

“I miss her so much.

“We didn’t know how lucky we were and are to have her, she is the best, strongest, funniest, happiest, loveliest, selfless, kind, thoughtful and beautiful person I know and I cherish every moment that I had with her.”

A justgiving page has been set up to help the family and has so far raised almost £6,000, far surpassing its £2,500 target.

Stephen said he is overwhelmed by the amount of support they have received from people.

He said: “People have been so lovely and it is such a comfort to us.

“We are so overwhelmed by people’s comforting words and we are gobsmacked at how many people have responded in the way that they have.

“Lisa would hate all this limelight, she never wanted to be the centre of attention.
